Abstract In this paper, the results of two different wire based additive-layer-manufacturing systems are compared: in one system Ti-6Al4V is deposited by a Nd:YAG laser beam, in the other by an arc beam (tungsten inert gas process). Mechanical properties of the deposits and of plate material are presented and evaluated with respect to aerospace material specifications. The mechanical tests including static tension and high cycle fatigue were performed in as-built, stress-relieved and annealed conditions. Generally, the mechanical properties of the components are competitive to cast and even wrought material properties and can attain properties suitable for space or aerospace applications.
